Y/n Luca is Dominique Luca’s little sibling. They are 15 years old and live with Dominique and have for a couple years now. They pretty much grew up around the team so they now them all pretty well and stuff. Jim Street also lives with Y/n and Dominique. Recently Y/n has been acting off, been coming home later than normal and stuff. (It’s the stuff going on from Stranger Things except it’s in LA and Y/n is in the middle of it. Takes place during season 4. All the characters are the same from Stranger Things except Maxine Mayfield doesn’t exist and Y/n is the fourth and final victim and seasons 1-3 have already happened. Y/n was the one who went missing from the beginning instead of Will). But no one knows anything about this stuff other than the group. Y/n’s brother and his team are all clueless about all of this. The only people who know the truth about everything that’s been going on the last couple years is Mike Wheeler, Dustin Henderson, Lucas Sinclair, Will Byers, Y/n Luca, Steve Harrington, Nancy Wheeler, Jonathan Byers, Jim Hopper, Joyce Byers, Murray Bauman, Robin Buckley, and now Eddie Munson.
